The problem is important in cryptography and other intelligence fields,
where it is important to distinguish signal from noise. Cryptanalysts
have devised algorithms for this purpose, to determine whether a given
text is in fact nonsense or not. These algorithms typically analyse the
presence of repetitions and redundancy in a text; in meaningful texts,
certain frequently used words—for example, the, is, and and in a text in
the English language—will occur over and over again.

However the Racter (?) programs, corporate PR and political speech writers seems to know this – heck, if you can test for it algorithmically you can generate it algorithmically, so manage to make
‘nonsense’ have the necessary redundancy to pass these tests and sucker-punch our cognitive processes and perform memetic subversion.

(As a sidebar, I’ll mention that my local talk radio, CFRB, has a show late Sunday where ‘saucertites’and the like are given a platform. They answer phone-in questions more rationally than the politicians, in fact they actually answer the questions the callers ask instead of sounding off on their own agenda. Perhaps this is why people believe the politicians and not the saucerites.)

Perhaps, as Neal Stephenson speculated in ‘Snowcrash‘, there is some Deep Language of our brains and some Politicians know fragments of it.
